WP820 Wireless Wi-Fi Phone

Been using this phone on its second day and it seems it works better with 2.4Ghz WiFi frequency. There’s little to no interefence and you can walk around with it. I haven’t tested carrying it for long since I work from home. Although it’s very convenient if you need to grab or do some stuff around the house with it. Plus it has a 3.5mm audio jack so you can just press the PTT button (I set it to mute button) if need be. As for the interface, it looks like a very basic cordless phone. Nothing fancy. Nothing bad with it. You can adjust the settings directly to the phone or use the web GUI. As for the lines. Yes, it can connect up to two lines only with transfer, hold, mute functionalities. You can switch between lines if you need to call with either accounts. You just need to press the Accounts soft key for this. It also has an alarm and calculator which is handy sometimes. The look and feel seems better than a China phone to be honest. I’ve seen a lot of China phones and I have no issues with its design. It’s a very basic phone like one of those Nokia 5210 models but taller. This is my first Grandstream phone and I’m fine with it. If you can’t carry a DECT phone or a deskphone for travel, I’d highly recommend this. I don’t see any other WiFi phone as cheap as this but still provide comparable voice quality. Cheers.

Purchased 2 phones September 2019. Configured by Carolina Business Phones, North Charleston SC. Both phones pre-configured by carrier. One phone had to be returned because charging wire DOA. Phone worked perfectly. Return process was swift. I then purchased two more phones. I use them at home with a detached office. Push button "walkie talkie" feature is a blessing. Love the clarity and volume. Android OS on phone and color screen. Long press on a key pops up a menu for special keys like *&^%$#@ handy for Wi-Fi passwords. This is an excellent phone but make sure your phone service can support the phone as it is new technology.

After a few months with 3 of these phones we are changing our review to one star. I can be at my desk using the phone and in the middle of the call it will drop wifi and drop the call. When wifi reconnects it will be on a different AP. The strange thing is that I can adjust the dB before the phone searches for a stronger signal in setting but it doesn't seem to work correctly. For example I can have the setting at -80dB, have the phone stationary with a signal of -50dB and suddenly it will drop and switch APs, which will drop the call as it takes about 5 seconds for the phone to reconnect. We are on the latest phone firmware of 1.0.7.30 and have looked through ad followed suggestions on the wifi roaming addendum on Grandsteam's website in our investigations. Our APs are Ubiquiti, BTW So it's a inexpensive voip wifi phone. The setup has a really, really nice GUI interface. If you have used other Grandstream products you will immediately realize that they didn't design the GUI in-house (which is a very, very good thing). On one phone we had audio problems, which can be hard to track down. The phone has some built in diagnostic features, including an audio loopback. By using it we quickly realized it was a hardware issue with the mic and swapped for a new phone on Amazon. Also, the belt loop thing is a joke. The phone is tall and when you sit down it will hit the chair and pop out of the holster. Overall there isn't much available for wifi voip phones at a normal price point....

It's not bad at all for a wifi based VOIP phone. setup is all via a GUI, and it is relatively straightforward.. Took only 2 or 3 minutes to connect with a FreePBX (asterisk) VOIP box, and it worked. audio quality is....well, it's Grandstream.. Not entirely sh**t... but not far from it. Of course that's the Grandstream we've come to know and love, right? the biggest complaint I have is the ergonomics of the buttons.. it's really got the typical cheap Chinese tech feel - buttons are sloppy, plastic is thin, etc.. Most of the time you have press the buttons hard (or harder than you should need to), and almost every call, i find that i've miss-dialed a number or two because of it. I've configured dozens of Polycom Kirk systems (now called Spectralink), and the quality difference is night & day... a 10 year old Kirk phone sounds night & day better than the Grandstream, and the feel is well, professional vs bush-league... if i could convince VOIP clients to put up with the Spectralink handsets' "old" GUI, i'd never place these in... but it is cheap, fast, and quasi reliable...

Cliente satisfecho el producto cumple perfectamente con su función, los materiales se sienten duraderos y el diseño es exactamente como se describe. Llegó a tiempo y sin ningún problema. Lo recomiendo ampliamente

Good voice quality. Reliable connection to my Samsung 3-node mesh WiFi in our large house. Even my wife likes the user interface. Took less than an hour to connect to my Grandstream UCM6102 VoIP PBX. Phone book (contacts) is functionally fairly robust but a bit awkward to use. Saving a caller ID as a contact saves the full ID as the first name and saves the caller ID number as Work Number. Gotta edit the contact to get it the way you want. Contact import file format not documented, so it's difficult to transfer phone book from other phone systems. Lots of ringtones, but most are funky; wish I could download my own ringtone. Web interface is decent. Don't yet understand paging and push-to-talk. Expensive when compared to DECT technology.

A unique product that I’m impressed with. Can’t speak to other reviewers comments about grand steam. It doesn’t O’Leary’s comment we’ll to the access point and isn’t that Smart about handover but it works and I couldn’t find alternatives. A bit of VOIP quality issues but I don’t blame the handset. I think that’s the ISP and my VOIP provider. Huge number of features and configuration including web set up and addrsss book import. Impressive. I’d buy again.

Bought two of these to try out and while they were easy to setup and seemed to work well, they are buggy. We set the admin password for the device using the web interface and we used a special character in the password. Out of nowhere, one of the devices stopped connecting to the wifi and since we hid all the admin settings on the handset to prevent end users from accessing it, we had to do a factory reset to fix it. Problem is, there was no key that allowed us to enter a special character from the keypad. Support suggested a few, none worked. This might be specific to the firmware we had on it at the time, but within 2 weeks of using it, it lost all settings and could not be recovered. Returned.

I am very happy with the product. I use it with my voip subscriber and the experience is very good, clear audio and good feature sets. I love the PTT feature but of course you need another WP820 to connect to. Since it is wifi I can place it on any wifi network and have a connected phone so it is very convenient.

Excelente, elegante, magestuoso!

This item is really difficult to set up , been trying all day and still not connected.. its a no for me especially as we are a business and can't get our calls ..

Ich habe mir das Telefon zugelegt als eines der wenigen, das folgende Kriterien erfüllt: - kommt ohne Gateway (Fritzbox, Speedport o.ä.) aus - nutzt WLAN statt DECT (da hätte ich Repeater oder eine Station gebraucht) - kann 2 SIP-Accounts verwalten - erfüllt den Wunsch nach einem "Festnetz-Telefon" Feeling (heutzutage Quatsch, aber die bessere Hälfte braucht das) Bin rundum zufrieden. Software ist nicht besonders sexy gestaltet, erfüllt aber ihren Zweck und die Einstellungen sind für technisch versierte Leute umfassend auf der Weboberfläche, etwas vereinfacht für weniger versierte Leute auf dem Telefon selbst. Man muss ein wenig sich einlesen, was die Einstellungen des Internet-Anbieters angeht, aber mit etwas Recherche ist das Telefon ruck-zuck lauffähig. Das Telefon, und Voice-over-WLAN generell, ist auch ein guter Test für die WLAN Qualität. Wenn der Ton etwas stottert unbedingt mal das WLAN prüfen, ggfs. ist 5 GhZ die bessere Option. Bin hoch zufrieden mit der Lösung aus technischer Sicht. Verarbeitung und Material ist für den Preis aber etwas unterwältigend, das muss man schon zugeben. Ich hoffe der Anbieter macht dies mit laufenden Sicherheitsupdates die nächsten Jahre wett.

Dieses Telefon ist mein erstes SIP Telefon. Ich wollte eine "Funkfrequenz" im Haus los werden und DECT an der Fritz!Box abschalten. Mit diesem Telefon ist das problemlos möglich. Die Konfiguration ist eigentlich simpel und im Netz gibt es genug How-To's dazu. Bei mir musste die Fritz!Box einmal neu gestartet werden. Hätte ich das nach dem Einrichten gleich getan, hätte ich mir erheblich Zeit gespart. Seither läuft das Telefon problemlos. Auch das Wechseln zwischen unterschiedlichen WLAN Access Points beim Wandern durch die Wohnung klappt und das Telefonat bleibt erhalten.
